TIME-CONTROLLED THERMOSTAT'IC' Moron.

Specification of Letters Patent. Patented Allg. 17, 1915.

Application filed July 12, 1909. Serial No. 507,072.

To all 'whom it may concern Be it known that I, EDWARD S. HALSEY,

of Lynn, in the -county of Essex and State of Massachusetts, haveini-ented certain new and useful Improvements in. Time-ControlledThermostatic Motors, of which the following is a specification.

In carrying out my invention I employ a clock with a time escapeni'ent,adapted to release, at the desired predetermined time, a

tension ligament that leads from the lthermostatic control to andoperates, the heaters dampers, or temperature dominating valves. And isdesigned especially to restrain or cut out of operation a class ofthermostatic devices which `are motors of sufficient power andsensibility to be used to operate directly through a rod or ligament, adistant dominating heatvalve, such as, the thermostatic motor describedin my Patent #916,861 of March 30th, 1909, which inotoi' has been chosento illustrate this application.

The object ofmy present invention is to provide a simple eifective meansof siinul taneously disengaging the control of the da v motor thuschecking-the .fire during the night; by a suitabletiming device, thatwill throw said motor into commission again at a predetermined time inthe morning and further to-provide that while the lire is checked up, itmay be engaged with and under the control of another'motor designed to4hold the temperature to a lower degree.

In the accompanying drawings, Figure 1 represents a front elevation ofmy apparatus. Fig. 2 represents a similar view on au enlarged scale ofvthe same. Fig. 3 representsa Aside elevation of the same. Figs. i and '5represent respectively front and rear views on a still larger scale ofthe time-1re- -leasiiig device. Fig. 6 is a side view of said device,while Figs.7 and 8 ai'e respectively,

fractional back and side views of the mechanism, showing the slidingoperating rod raised and hooked up to the time releasing stem of theclock. Fig. 9 is a sectional view looking down on Figs. 7 and S thesection being made directly at-the top of the clock. Fig. 10 shows theback arrangement of the clock when removed from the supporting Now to gointo detail The clock is a small round time piece with a time-setescapement located in the back portion of its case, as is quite common.To serve my purpose, the clock has the winding stem 1, of the timeescapement, extended ,so as to project a shortdistance through the clocksupporting metal back-plate 2. As is common in these small .metalclocks, in the back a recess is formed, for the winding and set keys, bythe extension of the shell of LAthe' case. In this recess a winding key3 is fixed on said stem -1,'each end of said key is recessed for thestop pin 4,' which is fixed to the back of the clock, so that saidkeyand stein can turn one-half revolution and no more and when wound upagainst said stop pin in the position shown in Figs. 7., S, 9 and 10,the top side of said stem is so formed or notched that the yoke 18 whichis soldered to the vertical sliding rod 6, can bel hooked up on it, asshown in Figs. 7, 8 and 9, but'at the time the escapement takes placethe winding Istem unwinds oiie-lialf turn when the other end of the keystrikes the stop pin, and the notched side of said stem,`

looks down while its slanting face looks'np as in Figs. 6 and 7, thusunhooking and letting fall the supported sliding rod `6 with theattached damper operating ligament 7.

. It should beunderstood that the thermostatic-motors D and N used toillustrate :this

rod G is raised and the crossfbar hooked onV the steml, thetemperature-controlling damper is operated directly b y the nightthermostat through the time mechanism .and the chain 7 attached to thei'od (i, thechain 9 being then slackened and the day thermostat beingout of commission for the night. It should now be obvious that with theclock supporting frame 2 supported and carried by the divergent chains Sfrom the night lthermostat N, and with the sliding rod (3,

linking ligament 9 leading from the day thermostat D to the checkdaniperthrough ligament 7 when the esca )ement stem is Wound at night'or othertimeJ and rod 6 is hooked up to rit, chain 9 is slackened and the `daythermostat thrown out of commission,

i while the damper and connecting-rod 6 are moved .up and down Withthe-.Whole time mechanism, by the then controlling and supis liberatedfrom sired nor lprovided the time releasing mechanism may be rigidlysupported by being i Fig. 3, in lwhen rod 6 is hooked up the heater ischecked, but there is no thermostatic control until the rod is liberatedand l the load again falls onthe single day thermostat as shown in Fig.2,

The clock isv attached to the supporting back plate 2 by hook A12, fixedat the top of the back plate which engages the hole 11 in theupper edgeof the clock case frame, -vvith the projecting stem 1 of the mechanismpassing through the hole 1 3 in back pl`ate 2, s ecuring it'in position,'but it can readily be swung forward and -then lifted off thefhook toWind and set.`

To Cushion the an vof the rod sana at- :tached damper or Weights I mayemploy the 'two brass, cylinders 14and15 made air tight at l,the bottomby' soldering tothe foot of plate 2 as shown in Figs. 5, 6. and 7, 'saidcylinders acting as an air dash for the semiconical, close-hitting ybutfrictionless, iexibly mounted, piston heads 16 and 17, mounted `bywire'stems' soldered to cross yoke 18v which .in turn is soldered to theupper end of rod '6 These dash pots are not absolutely essential and4may be omitted Without ai'ecting the fundamentalsof the invention. Theapparatus as it appears Without them is 'shown in Fig. 3.

I am aware lthat time controlling devices` for starting up a heater in:the morning are notneW.

What I claim iszl. In conjunction With a mechanical thermostatic motor aclock With time set escapement'; an operating ligament leading from saidmotori-to a temperature dominating valve;"la device releasable by saidclock mechanism at 'apredetermined time; for hooking up said operatingligament thereby relieving said thermostatic motor of tension and dutyuntilreleased by said clock.
